Scalings of nonlinearity in the edge plasma and its connection to transition thresholds

Christian Gabriel Theiler

Nonlinear transfer processes between large-scale edge flows and the ambient broadband fluctuations have been shown to play a significant role in the dynamics of edge turbulence, including spreading power from coherent modes and suppressing turbulence at th ...

Experimental investigation of a Thermally Driven Heat Pump based on a double Organic Rankine Cycle and an oil-free Compressor-Turbine Unit

Daniel Favrat, Jürg Alexander Schiffmann, Jonathan Demierre, Johannes Wegele

This paper presents the experimental investigation of a concept of Thermally Driven Heat Pump (TDHP), based on the coupling of a vapor compression heat pump cycle and an Organic Rankine Cycle (ORC). The studied concept uses a single stage centrifugal compr ...

Plasmonic heating with near infrared resonance nanodot arrays for multiplexing optofluidic applications

Rachel Grange

In this work, we show local laser-induced heating in fluids with gold nanodot arrays prepared by electron-beam lithography that cover resonances in the near infrared spectral range from 750 nm to 880 nm. We utilize two approaches to demonstrate thermal eff ...

Hydro-acoustic resonance behavior in presence of a precessing vortex rope: observation of a lock-in phenomenon at part load Francis turbine operation

François Avellan, Arthur Tristan Favrel, Christian Landry, Andres Müller, Keita Yamamoto

Francis turbines operating at part load condition experience the development of a cavitating helical vortex rope in the draft tube cone at the runner outlet. The precession movement of this vortex rope induces local convective pressure fluctuations and a s ...

Advanced Control of Electrochromic Windows

Nicolas Morel, Nikolaos Zarkadis

In our research we use the technology of electrochromic (EC) glazing to maximize the use of daylight and minimize the energy consumption in buildings while preserving visual and thermal comfort of the users. We propose an advanced automatic control of EC w ...

Active House: new buildings for sustainable architecture

Arianna Brambilla

Buildings consume more than 40% of all the energy we use, and about 50% of it is used for the conditioning systems, for this reason it is important to work on the energy demand, improving the buildings behaviour, in order to save the environment of the fut ...

Sensor placement for predicting airflow around buildings to enhance natural ventilation

Ian Smith, Maria Papadopoulou

It is a challenge to design buildings that are both energy efficient and healthy. The factors that contribute to energy efficient and healthy buildings are related to both indoor and outdoor conditions. For example, the airflow around naturally ventilated ...
